Error after upgrade successful

Encounter error after upgrade successful from version 1.7.4 to 1.8.1 (with docker)

Error Details:

  1. After upgrade successful, click on the link “continue” then it show me the error message like this:
    Configuration Error

Problem copying provided file into the Library Folder

  1. owner of /var/www/cms/* already changed to www-data
  2. mysql table - setting: already update the LIBRARY_LOCATION to /var/www/cms/library

Please advise.

Thanks

Could you please confirm that you’ve followed every step under ‘Switching to Docker’ from here http://xibo.org.uk/manual/en/upgrade.html ?

Your library location needs a trailing slash on it - ie /var/www/cms/library/

@Peter
Ya, I had read the ‘Switching to Docker’ article before proceed.
But, i have added a little bit extra steps for database migration and upgrading.

@alex
finally it can work after i add the trailing slash.

Thanks.
